Abstract
Embodiments of an apparatus are disclosed, the apparatus comprising: a substrate having a first end and an opposite, second end; a plurality of sensors proximate to the first end of the substrate, each sensor including: a first electrode; a second electrode at least partially surrounding the first electrode; and an active sensing element over the first electrode, a surface of the active sensing element being functionalized detect analytes in a sample derived from an environmental source; a plurality of contact pads proximate to the second end of the substrate, each contact pad being conductively coupled to the first electrode or the second electrode of a corresponding sensor in the plurality of sensors; and a cartridge surrounding the plurality of sensors and providing an enclosed space to contain the sample over the plurality of sensors.
